AIRE Ancient Baths Opens Upper East Side Spa at 305 E 61st

AIRE Ancient Baths has planted a new sanctuary on the Upper East Side at 305 E 61st St, offering a six‑bath thermal circuit and the brand’s signature suspended Flotarium, a saltwater bath that appears to float mid‑air. The company describes the location as housed in a 120‑year‑old building that once stored MoMA’s art and silver collections, and marketing materials call the footprint “over 10,000 square feet,” while an on‑site account lists the sanctuary at 9,600 square feet.

Vaulted ceilings and loft‑style architecture shape the circulation, with exposed brick and preserved timber beams creating the softly lit, candlelit atmosphere AIRE markets as “a temple dedicated to the relaxation of body and mind.” Beaire, the New York operator for AIRE, highlights the suspended Flotarium and the neighborhood context among historical landmarks and museums when inviting guests to “be guided by candlelight while the aroma of orange blossom fills the air.”

The thermal offering at the 305 E 61st address follows AIRE’s familiar format: baths at different temperatures, a steam room, a jet bath, and the suspended saltwater Flotarium. Guest procedures emphasize privacy and ritual: staff send a check‑in email before visits, guests show ID, don rubber bracelets that indicate time and treatments, and phones are collected on arrival. A visiting blogger noted the facility’s “vigorous whirlpool” with slots large enough to recline, which an attendant described as an “aqua massage,” and cautioned that phones are locked up and that photography inside the baths is not permitted.

User reviews captured on the venue listing praise the thermal variety and staff guidance by name. Amanda V. wrote that she “appreciated the different temperature baths, including the cold plunge, hot tub area, and steam room.” Nigora R. singled out locker room attendant Ellen, saying, “I really appreciated Ellen, the locker room attendant, because she answered all my questions, and walked me through everything.” Lynn M. also highlighted “the different temperature pools” as a visit highlight.

The Upper East Side opening comes as AIRE continues to deepen its U.S. presence and expand its Tribeca flagship. A recent rework of the Tribeca site added 5,600 square feet and four new baths, plus heated marble beds and an expanded roster of 11 massage rooms. Amadeo Serra, CEO of AIRE Ancient Baths, framed the growth as a longer term commitment to New York, saying that Tribeca “is where our journey in the U.S. began,” and that the work there follows “the recent opening of our Upper East Side location.”

Practical details for visitors: the UES spa lists hours Monday through Thursday 10:00 AM to 11:00 PM, and Friday through Sunday 8:00 AM to 11:00 PM; reservations and inquiries can be made by phone at +1 332‑244‑4191 or by email at nyues@beaire.com. With a Flotarium hovering over a thermal circuit inside a repurposed MoMA warehouse, AIRE’s Upper East Side outpost positions itself as an intimate, museum‑adjacent refuge for New Yorkers seeking structured cold and heat work alongside signature float and treatment offerings.
